BACKGROUND OF THE INVENTION Field of the Invention

The present invention is directed generally to an eyewear platform, andmore particularly, to the design of a releasably attachable augmentedreality (AR) system that meets the demands of consumers and enterprise,while providing features including, but not limited to, augmentedreality or mixed reality. Additionally, certain aspects of the inventiondisclosed herein can be applied to augmented reality or mixed realityeyewear in general.

It is an adage in the optical industry that fashion trumps function.Even if a type of eyewear is highly functional, if it is notfashionable, the eyewear will not be purchased in quantity by consumers.There are literally hundreds, if not thousands, of eyewear frame styles.(See, e.g., FIGS. 5, 6.) Consumers like and demand selection whenpicking out new eyewear. Electronic eyeglasses of all types havesuffered from this consumer hurdle. Building electronics into theeyeglass frame increases the cost of goods, cost to the consumer, andthickness and weight, and reduces the fashion selection of eyewearavailable for consumers to choose from. By way of example only,Augmented Reality (AR) eyewear (mainly in the form factor of a headsetor goggles) today can weigh up to 500 grams, compared to customaryeyeglasses which weigh 20 grams to 40 grams. Such AR headsets or gogglesretail for up to $3,000 or more. They are bulky, heavy, not fashionablelooking, and expensive. Smart eyeglasses with a heads-up display areavailable in a very limited number of styles and colors. What is neededis a new platform for providing AR and or Mixed Reality (MR) forconsumers and enterprise to use, while maintaining an acceptablefashion, look, weight, selection of eyewear, and cost.

DESCRIPTION OF RELATED ART

As computer systems have been miniaturized and have higher performanceand display apparatuses and image communication technologies haveadvanced, wearable devices that can be worn by a user have beendeveloped. For example, smartwatches wearable on the wrist, smart bandswearable on the head, arm, or foot, smart eyewear worn on the head, etc.have been developed.

The trend toward miniaturization of computing hardware, peripherals, aswell as of sensors, detectors, wireless communication and image andaudio processors, among other technologies, has helped open up a fieldsometimes referred to as “wearable computing.” In the area of image andvisual processing and production, in particular, it has become possibleto consider wearable displays that place a very small image displayelement close enough to a wearer's eye such that the displayed imagefills or nearly fills the field of view, and appears as a normal sizedimage, such as might be displayed on a traditional image display device.The relevant technology may be referred to as “near-eye displays.”

Near-eye displays are fundamental components of wearable displays, alsosometimes called a head-mountable device or a “head-mounted display.” Ahead-mountable device places a graphic display or displays close to oneor both eyes of a wearer. To generate the images on a display, acomputer processing system may be used. Such displays may occupy awearer's entire field of view, or only occupy part of wearer's field ofview. Further, head-mountable devices may be as small as an electroniccontact lens, a pair of smart eyeglass lenses, or as large as a helmet.

A head-mountable device may provide a graphic display and may bedirected to transition from one state to another, such as to transitionfrom and “on” state to an “off” state.

Such displays may be used for Augmented Reality and/or Mixed Reality asexplained herein. They are also used for Extended Reality, referred toas XR. XR is the overarching category of one or more of a smartphone,mobile Virtual Reality headset, and/or Augmented Reality unit, such asthe embodiment(s) described in the current application. Accordingly, thevarious embodiments disclosed herein can be used for certain forms ofXR.

SUMMARY OF THE INVENTION

An AR Unit is provided, whereby the AR Unit utilizes existing eyewear asan attachment platform, and whereby the AR Unit is attachable to anddetachable from a plurality of different eyewear having different shapesand sizes, whereby a portion of the AR Unit rests on the top of theeyewear, and whereby the AR Unit can provide unobstructed vision whenthe wearer is looking straight ahead. In certain embodiments, an opticalcombiner of the AR Unit is located at or above the upper edge of thepupil of the wearer. Said another way, in certain embodiments theoptical combiner of the AR Unit is located above, immediately above, orhigher above the line of sight of the wearer. (See, e.g., FIGS. 28-30)In other embodiments, the optical combiner is located within the line ofsight of the pupil 2910. (See, e.g., FIG. 29.)

The AR Unit can be comprised of the following major parts: 1) AR mainunit, 2) AR unit housing, 3) AR unit housing covering, 4) AR unitelectrical conductive tether and electronic module that can, by way ofexample only, reside behind the wearer's head or neck, 5) OpticalEngine(s), 6) Light Engine(s), 7) Vision System, 8) associatedelectronics, 9) camera(s) or image capture device(s), and 10) auditorysystem.

Utilizing the invention, a limited number of AR Unit shapes can fit mosteyewear frame styles and sizes. In fact, five or fewer AR Units can fitmost eyewear frame styles. This can be accomplished, by way of exampleonly, by one of: the provider of the AR unit at the point of sale or thepurchaser of the AR Unit for his or her eyewear, whether the eyewear benew eyewear or existing eyewear. The AR Unit's main body can fit on thetop of an eyewear frame and can be adjusted or conformed to the topcontour or shape of the eyeglass frame front's top. In certainembodiments, compressible material can be positioned between the top ofthe eyewear frame and the bottom of the AR Unit, or in a recess in thebottom of the AR Unit to wholly or partly fill in any open space thatmay exist or help achieve acceptable fit. In other embodiments, a façadecan be placed beneath the AR Unit and above the top of the eyewear framebridge to fill in any open space that may exist.

The AR Unit can provide monocular or binocular augmented reality. Incertain embodiments, the horizontal length of the AR Unit (main body) isthe same as or is shorter in length dimension than the horizontal lengthdimension of the eyewear frame front that is supporting it, and themiddle of the horizontal AR Unit (main body) dimension is of a greatervertical height dimension than either end of the horizontal dimensionlength of the AR Unit (main body). (See, e.g., FIG. 8.) The front of theAR Unit main body can extend forward in front of and above the eyewearframe front to which it is attached. The rear of the AR Unit main bodycan extend slightly rear of and above the frame of the frame front towhich it is attached. In most embodiments, but not all, the front of theAR Unit's main body extends forward from the AR Unit's main body morethan that of the back of the AR Unit's main body relative to the eyewearframe front to which it is resting.

In certain embodiments, five or fewer AR Unit main body designs havingone or more flex joints or made of a flexible or shapeable material canfit upwards of between 66.67+% and 80%, for example, of all eyewearstyles and sizes. (See, e.g., FIG. 7.) In certain embodiments, the ARUnit main body is made of a flexible material that houses one or morerigid electronic and/or optical module(s). In certain embodiments, theAR Unit main body has a recess in the bottom side of the AR Unit. The ARUnit main body can have a recess that is of a length that accepts aportion of a top of an eyeglass frame. The AR Unit main body can have arecess that is of a length that accepts the top of an eyeglass frame. Incertain embodiments, the bottom of the AR Unit can accept a pin from aconformable or compressible material. (See, e.g., FIGS. 9, 10.) Therecess can accept a male ridge located on the top surface of aconformable or compressible material. (See, e.g., FIG. 9.) In certainembodiments, the AR Unit includes a permanent, integral, or removableconformable or compressible material. (See, e.g., FIG. 13.) In certainembodiments, the conformable or compressible material has a male ridgeon its superior top surface that fits within a female recess of thebottom of the main AR Unit portion (see, e.g., FIG. 13), or theconformable or compressible material has a female recess that is on thelower bottom surface of the compressible material that fits over aportion of the top edge of the eyewear. The AR Unit main body maycomprise a conformable or compressible material that extends across themajority of the AR Unit main body (see, e.g., FIG. 13), or that islocated above the bridge of the eyewear (see, e.g., FIG. 14). Thecompressible material can be in one or more pieces.

In other embodiments, a bendable member is housed within or attached toa flexible portion of the AR Unit. The flexible portion of the AR Unitrests on top of an eyewear frame front. The bendable member can havelittle to no material memory, meaning that once it is bent it does notreturn to its original shape. The bendable member can be reshaped so toreshape the flexible portion of the augmented reality device. Inaspects, the AR Unit main body is constructed of materials that permitbeing reshaped by a third party or the wearer to fit his or her eyewearframe and/or to allow for a customized look preferred by the wearer orthird party when attached to his or her eyewear. It should be pointedout, that this patent disclosure anticipates that the seller of the ARUnit and/or an optical technician can also fit or shape the AR Unit forthe eyewear of the wearer to the satisfaction of the wearer. Also, thispatent disclosure anticipates that the purchaser can also fit or shapethe AR Unit for his or her eyewear to their satisfaction.

In still other embodiments, the covering of the AR Unit is bendable orshapeable, while the internal electronic module and/or electronics areleft largely unaltered. This permits the AR Unit's bottom to be reshapedwithout affecting other parts of the AR Unit. In other embodiments, theelectronics within the AR Unit are housed within mostly rigidstructures. These structures are divided into separate structuralcompartments permitting the AR Unit to be reshaped while leaving theelectronics largely intact.

The AR Unit main body houses one or more electronic module(s) andthereby fully or partly covers and/or houses the electronic module(s).The AR Unit main body can house one or more of: conformable, bendable,formable, and/or malleable members. In aspects, when a singleconformable member is utilized, the electronic module or modules areseparate from the single conformable member. (See, e.g., FIGS. 44,51-52.) The AR Unit Body may house an electronic module(s) having one ormore of: conformable portions, malleable portions, and/or bendableportions. The one or more of: conformable, malleable, bendable, and/orformable member(s) or portion(s), can be adjusted to shape the AR Unitmain body or portions of the body so that it is complementary to theeyewear frame front, on top of which the AR main body or AR Unit rests.The bendable materials can be made of any material that can be bent to ashape while retaining the shape to which it is bent; by way of exampleonly, a thin metal. Such bendable materials having little to no memory,by way of example only, can include: tin, aluminum, polycarbonate, PMMA,or polystyrene. The following are, by way of example only, flexiblematerials that the AR Unit main body or its outer covering can be madeof by way of example only: polyterephthlate, urethane, polybutadiene,polyisoprene, cross linked hydrogel, and/or rubber. The following are,by way of example only, malleable materials that may be used to shapethe AR Unit main body. The malleable materials that have re-formablememory, by way of example only include: malleable thermosets based onpolyimine networks, cross-linked polycaprolactone, or polyurethanes.

In certain embodiments, the AR Unit main body comprises an arm or arms.Each arm secures the unit to one of the two eyewear temples. Each armcan be attached to an eyewear temple by way of any mechanical attachmentmeans, by way of example only, strap, hook, snap, magnet, male/femaleinterface, and/or Velcro. In one embodiment, by example only, an arm canhave a series of apertures which permit the arms to be adjusted. (See,e.g., FIGS. 16-17.) An arm can have two or more apertures. The aperturescan be circular, elongated or of any shape. A male member that isconnected to the eyewear temple permits engaging with an aperture of thearm. By choosing different apertures, the arms can be adjusted inlength. In other embodiments, the arms can comprise a small magnet whichthen engages with a track comprising a ferromagnetic material or anothermagnet located on or about the temple. In a preferred embodiment, thearm attaches directly or indirectly to the inside side of the eyeweartemple. The track can be attached to the eyewear temple or incorporatedwithin the side of the eyewear temple. In other embodiments, the armscan comprise a ferromagnet material which then engages with a magnetlocated on or about the temple. In a preferred embodiment, the armattaches directly or indirectly to the inside side of the eyeweartemple. The track can be attached to the eyewear temple or incorporatedwithin the side of the eyewear temple. In still another embodiment, twomagnets can be used; one on the arm, and one that is embedded in orattached to the eyewear temple. In certain embodiments, the arm(s) areattached directly to the hinge which attaches a temple to the eyewearframe front.

In certain embodiments, the arm(s) can be attached to the AR Unit mainbody by, for example, a hinge or swivel joint. (See, e.g., FIG. 16.)This allows an arm to be rotated up or down depending upon the manner towhich it attaches to the eyewear temple. For clarity, the arms of the ARUnit can be adjustable in length and/or also in positioning. Thispermits for attaching the AR Unit main body to a wide variety ofdifferent styles, sizes, and shapes of eyewear.

The AR Unit main body can be expanded or shortened horizontally to fit alarger or smaller frame front, respectively. The manner which the ARUnit's horizontal length can be expanded or shortened is, by way ofexample only, a pin or pins that pull in or out of each of thehorizontal ends of the AR Unit's main body. In other embodiments, thehorizontal length of the AR Unit's main body can be expanded orshortened by way of the covering of the AR Unit's main body beingseparated into two or more sections in a manner which it can be pulledapart or pushed together. In preferred embodiments, the AR Unit mainbody supports one or more optical windows, including two opticalwindows. When two optical windows are utilized, in aspects, one opticalwindow can be up to 60 mm wide (horizontally) and up to 50 mm tall(vertically). In certain embodiments, one optical window can be used. Inother embodiments, each optical window can be 20 mm or less wide(horizontally) and 20 mm or less tall (vertically). When one opticalwindow is utilized for both eyes, the one optical window can be up to150 mm horizontally and up to 50 mm tall (vertically). An optical windowor a portion of the optical window(s) can be, support, comprise,include, or act as a partial reflector or a beamsplitter. For purposesof clarity, a partial reflector as used herein is meant to facilitatethe same function; namely, to allow the transmission of a certain amountof light while reflecting a certain amount of light (see, e.g., FIG.56A). An optical window or a portion of the optical window(s) can be,support, comprise, include, or act as an optical combiner or combiner.For purposes of clarity, an optical combiner and combiner as used hereinare meant to facilitate the same function; namely, to cause two or moreimages to be superimposed on one another or within the same view, suchas when a virtual image is combined with a real image as perceived by awearer of a system. In certain embodiments, an optical window can have awidth on one end of 3 mm to 7 mm for a certain distance and then enlargeto that of a 7 mm to 15 mm square, round, circle, oval, or some othershaped zone to which the pupil of the wearer's eye will look through. Incertain embodiments, an optical window can be 10 mm-60 mm wide. Incertain embodiments, an optical window can be 10 mm-50 mm high(vertically). An optical window can be taller vertically than it is widehorizontally. (See other possible dimensions, shapes, and sizes in,e.g., FIGS. 18-21.) The thickness of the optical window can be 0.25microns to 3.0 mm thick. The materials can be made of, by way of exampleonly, transparent soft, semi-rigid, and/or rigid materials. An opticalwindow can be shorter vertically that it is wide horizontally (see,e.g., FIG. 31). In certain embodiments, one long horizontal opticalwindow can be used that wholly or partly covers both eyes and iscontinuous over the nose of the wearer (see, e.g., FIGS. 32-33). Whenone optical window is utilized, a notched area is provided in the bottomedge of the optical window for clearing an area around the nose of thewearer (see, e.g., FIGS. 32-33). In this case, the long continuousoptical window can be over 100 mm in the horizontal dimension. When theoptical window is one long continuous unit, certain portions of theoptical window can comprise, support, include, or have embedded acombiner(s), beamsplitter(s), or partial reflector(s). In certainembodiments, the previously disclosed one long continuous optical windowcan be split over the bridge of the nose to break the window into twowindows so that each can be adjusted independently of one another (see,e.g., FIGS. 31, 50).

In certain embodiments, an optical window and/or optical combiner can bethat of a top down optical window or optical combiner. The opticalwindow and/or optical combiner can be attached to the AR Unit main bodyand extend down and in front of a lens housed by the eyewear frame towhich it is attached or is resting thereupon. In certain otherembodiments, the optical window and/or optical combiner can be attachedto the AR Unit main body and extend down and behind a lens housed by theeyewear frame to which it is attached or is resting thereupon. Incertain other embodiments, the optical window and/or optical combinercan be incorporated within the lens housed by the eyewear.

In certain embodiments, the bottom edge of the optical window is locatedat or above the top edge of the pupil of the eye(s) of the wearer. Inother embodiments, the bottom edge of the optical window is located suchto cover the bottom edge of the pupil. When the bottom edge of theoptical window is located at or above the top edge of the pupil of theeye of the wearer, the wearer can experience unencumbered vision withnormal gaze when looking straight ahead. When the bottom edge of theoptical window is located at or above the top edge of the pupil of theeye of the wearer, the line of sight of the wearer is unencumbered bythe optical combiner. In such an embodiment, when the wearer desires tosee an augmented or mixed reality image, the wearer tilts his or herchin down between 5 and 45 degrees while keeping his or her eyes lookingstraight ahead in a horizontal manner relative to the ground on whichthey are standing (see, e.g., FIG. 57).

An optical window, or portions thereof, can made of a transparent,mostly transparent, translucent, mostly translucent, semi-transparent,transmissive, and/or partially transmissive material. All or a portionof the optical window can be made of a light transmission changingmaterial such as, by way of example only, photochromic material,electrochromic material, and/or thermochromic material.

In certain embodiments, an electrical conductive tether and electronicmodule is part of or connected to the AR Unit. These can, by way ofexample only, reside behind the wearer's head or neck. In aspects, theelectrical conductive tether connects certain electronics not housed inthe AR Unit main body with those housed in the AR Unit main body. Thisallows for electronic components to be offloaded or located separatelyfrom the AR Unit main body and housed on or within the electricalconductive tether and electronic module. By way of example only, one ormore of the following can be electrically connected to the electricalconductive tether or electronic module: power source, main power source,rechargeable battery, battery, coil, source of wireless communication,controller, transceiver, transmitter, receiver, GPS, CPU, memorystorage, flash memory, random access memory, EEPROMs, earbud, hearingaid, assisted hearing device, wifi chip, Bluetooth chip, vibrator,communication system, antenna, audio system, radio, sensor, ASIC,switch, auditory system, sensor(s) and/or image processor. This reducesthe size and weight of the AR Unit main body. This reduced size helpswith making the AR Unit more fashionably acceptable and/or comfortableto the wearer when attached to the eyewear worn by the wearer. Also, thereduced weight helps with comfort of wearing the AR Unit when attachedto the eyewear worn by the wearer.

The AR Unit can comprise an auditory system. The auditory system canutilize ear buds. The ear buds can be connected by a wired connection tothe AR Unit. When wired to the AR Unit, the ear buds connect in most butnot all cases to the electronic tether. The ear buds can be wirelesslyconnected to the AR Unit. The auditory system can utilize boneconduction for audio transmission. A personal assistant can be part ofthe auditory system.

By way of exampleonly, when a monocular virtual image is communicated to the wearer, onlyone optical combiner is required. When a binocular virtual image iscommunicated to the wearer, two optical combiners are required. Saidanother way, a monocular AR unit requires one optical engine and onelight engine, whereas a binocular AR Unit requires two optical enginesand two light engines.

An optical window can be a transparent or mostly transparent substrate.An optical window can be made of, by way of example only, plastic orglass. An optical window can be made of, by way of example only, arigid, semi rigid, soft, and/or flexible material. An optical window canbe planar or curved. In certain embodiments, the optical window is flat.In other embodiments the optical window is curved. The curve can besimilar to an eyeglass lens front surface. In still other embodimentsthe optical window is curved to match the front convex surface of thespectacle lens to which it sits in front of. When used as a substrate,the optical window can have the same refractive index or within therange of 0.01-0.05 refractive index units and more preferably within therange of 0.01-0.03 refractive index units of the material as the memberthat is attached. An optical window can transmit an image from aprojector or a display, such as the embodiment shown in FIG. 56A or 56B,or an optical window can transmit an image internally through thematerial the optical window is made of, such as the embodiment shown inFIG. 56C (e.g., a transparent OLED display or an image created by anexternal display and transmitted to the optical window using animage-preserving waveguide array). An optical window can support thetransmission of an image from a projector or a display, such as if itincludes a partial reflector, or an optical window can support thetransmission of an image, such as if it includes a see-through OLEDdisplay or an image created by an external display and transmitted tothe optical window using an image-preserving waveguide array. An opticalwindow can itself also reflect an image from a projector or display. Anoptical window, or portion(s) thereof, can be that of an opticalcombiner or combiner. An optical window, or portion(s) thereof, cansupport an optical combiner or combiner. An optical window can beantireflective coated on one or both surfaces. An optical window can beremovably attachable to the AR Unit, such as magnetically to the AR Unit(see, e.g., FIGS. 50-52 at 5030, 5130, and 5230). An optical window canbe removably attached mechanically or permanently attached to the ARUnit. An optical window can be one continuous optical window for botheyes (see, e.g., FIGS. 32-33).

In certain embodiments, an optical window can be locatedin front of the eyeglass lens, furthest away from the eye of the wearer.In certain other embodiments, an optical window is located behind theeyeglass lens closest to the eye of the wearer. In still otherembodiments the optical window can be embedded within the eyeglass lenshoused by the eyewear.

In certain embodiments, the bottom edge of the optical window is locatedat or above the top edge of the pupil of the eye of the wearer. In otherembodiments, the bottom edge of the optical window is located to coverthe bottom edge of the pupil. When the bottom edge of the optical windowis located at or above the top edge of the pupil of the eye of thewearer, the wearer can experience unencumbered vision with normal gazewhen looking straight ahead. When the bottom edge of the optical windowis located at or above the top edge of the pupil of the eye of thewearer, the line of sight of the wearer is unencumbered by the opticalcombiner. In such an embodiment, when the wearer desires to see anaugmented or mixed reality image, the wearer tilts his or her chin downbetween 5 and 45 degrees while keeping his or her eyes looking straightahead in a horizontal manner relative to the ground on which they arestanding. (See, e.g., FIG. 57.) In FIG. 57, the wearer's line of sight5710 is shown by the dotted line and the optical combiner is shown by5720. As shown in the figure, when the wearer is looking straight ahead,the optical combiner 5720 is above his pupil(s) and out of the line ofsight 5710. When he tilts his chin down and looks ahead, his line ofsight passes through the optical combiner 5720.

In still other embodiments the optical window can cover the pupil of thewearer when the wearer is looking straight ahead. In these embodimentsthe optical window is larger than in the embodiments where the wearermust tilt his or her chin down to see through the optical combiner. Whenthe optical window covers the pupil of the wearer when the wearer islooking straight ahead, the optical window can be one of: the same sizeas that of the eyewear frame lens outer dimensions, smaller than theeyewear frame lens outer dimensions, or larger than the eyewear framelens outer dimensions.

Both the optical window(s) and the eyeglass lens(s) may be coated withan antireflection coating. In certain embodiments an index matching orindex averaging oil can be applied between the front of the eyeglasslens and the back of the optical window to enhance light transmissionbetween the eyeglass lens and the optical window.

An optical window can support a reflector or partial reflector. Thereflector may provide optical power.

An optical window can support, include,and/or comprise a lightguide. An optical window may be a waveguidearray. An optical window may be a lightguide. An optical window cansupport, include, be, and/or act as a display. The display can be, byway of example only, a see-through OLED display. An optical window cansupport, include, be, incorporate, and/or act as a lightpipe 1910, 2110,as well as an image expander, diffractive optic(s), and/or mirror(s)1920, 2120. (See, e.g., FIGS. 19, 21.)

An optical window can have steps on its surface. These steps can be inthe upper 50% of the height of the optical window for accepting arotating mechanical member providing upward and downward movement of theoptical window. An optical window can be adjustable from one position toanother, by way of example only, an optical window can be moved in oneor more of the following directions: horizontally, vertically,clockwise, counter clockwise, rotated such that its bottom edge is movedfurther away from the front surface of an eyeglass lens or moved closerto the front surface of an eyeglass lens.

A portion of the upper 50% of the vertical height of the optical windowcan be opaque with the remaining up to 50% being transparent. Theoptical window can darken when in sunlight. An optical window can bedarkened and/or lightened in light transmission. Such techniques fordarkening and lighting the optical window are well known in the art. Byway of example only, an optical window can be photochromatic,thermochromic, electrochromic, mirror coated, clear, darkened bydichroic liquid crystal, and/or tinted.

In certain embodiments, the AR Unit can have two optical windows andeach optical window can be, include, and/or support an optical combiner.Each optical window can support one fiber optic bundle. Each opticalwindow can support a fiber optic bundle and an optical combiner. Thefiber optical bundle can be superior to that of the optical combiner.

In certain embodiments, the optical window be, include, and/or support atransparent OLED. The optical combiner can be, include, and/or support asee-through OLED. A transparent OLED or TOLED can be that of asee-through OLED. In certain embodiments the optical window can be,include, and/or or support a see-through OLED comprising a microlensarray. In certain embodiments the optical window can be, include, and/orsupport a microlens array attached to a see-through OLED. Thesee-through OLED and/or microlens array can be curved in a similarmanner as the front surface of the eyeglass lens to which it is in frontof. Such a curve can be similar to the base curve of such eyeglass lens.When the AR Unit utilizes a see-through OLED for its optical combiner,the AR Unit's main body can be reduced in size and weight. This is dueto the fact that the AR Unit's light engine and the optical engine canbe reduced in number of components and size. In addition, the energy usecan in most cases be reduced as well. In certain embodiments, eachoptical window can support a waveguide and see-through OLED. In certainembodiments, each optical window can support a lightguide andsee-through OLED. In certain embodiments, each optical window cansupport a fiber optic bundle and see-through OLED. In certainembodiments, an optical window can support a see-through OLED. Incertain embodiments, the see-through OLED is an optical combiner. Incertain embodiments, an OLED is a light source for the light engine. Incertain embodiments, the see-through OLED is a portion of the opticalengine. In certain embodiments, the see-through OLED is the opticalengine. In certain embodiments, the see-through OLED is the light sourcefor the light engine and is also a portion of the optical engine. Incertain embodiments, the see-through OLED is the light source for thelight engine and is also the optical engine.

The AR Unit can support two optical combiners, one for each eye. The ARUnit can support one optical combiner. The optical combiner can be linedup relative to a pupil of the wearer.

An edge of the optical combiner can be at the peripheral edge of thevirtual augmented reality bubble defined by the field of view that iscreated by the unit's optical combiner within a real image and can befeathered (or smoothed out) by way of a refractive index gradient formedwithin the material of the optical combiner effectively reducing thebrightness of the augmented reality bubble at its periphery. By way ofexample only, if the section of the optical combiner has an index ofrefraction of 1.8, refractive index would transition from 1.8 at thecenter of the optical combiner to a refractive index of 1.5 at the outeredge of the section of the optical combiner. This change in refractiveindex may be applied over a length of 0.5 mm to 3.0 mm, preferably 0.5mm to 1.0 mm. A short refractive index gradient serves to reduce theintensity of the edge without affecting the brightness of the overallvirtual image. Such an index gradient can be fabricated by any meansknown in the art for creating such an index gradient, including by wayof example only, deposition of an additional layer of a second material.Such a second layer may be of thickness 5 microns to 500 microns,preferably 25 microns to 100 microns.

When the AR Unit main body is flexed or bent to conform to the top ofthe eyewear frame front, this may cause the optical windows and othervisual, light, and optical components to rotate out of alignment withrespect to the optic axis of the eye. The optical windows, for example,could become rotated and not straight up and down vertically uponconforming the AR Unit main body or outer covering to properly fit orlook best upon the top of the eyewear frame front. Should this occur, incertain embodiments, either the optical window or the connection to theoptical windows can be rotated in the appropriate direction to allow forthe optical windows to become realigned vertically. This adjustmentrequires a rotatable fixture that can rotate along one axis, two axes orthree axes. Also, each optical window can be adjustable by way ofrotating clockwise or counter clockwise.

In certain embodiments, the vertical height of the optical combiner ofthe optical window can be adjustable by way of edging the waveguideoptical combiner of the optical window to the desired vertical heightfor a given frame eye size and style relative to the wearer's pupil. Incertain embodiments the vertical height of the optical combiner ismanufactured to be of the appropriate height. The displayed augmentedreality image can be programmed to be displayed in relation to theusable optical combiner dimensions (vertical and horizontal) thatcontrol the field of view. In preferred embodiments, the bottom edge ofthe optical combiner is set above the top edge of the pupil at primarygaze. The optical window or optical combiner may also be angled suchthat the bottom of the optical window or optical combiner can be rotatedforward and then up and over, as shown at 2230 in FIG. 22. In certainembodiments, the bottom edge of the optical window or optical combiner(when fit above the top edge of the pupil of the eye of the wearer) canbe rotated away from the front of the eyewear lens. By doing this, itoffsets certain of the angle of the head tilt when the wearer's chin istilted down and the eyes continue to look forward and straight ahead toexperience augmented reality. By offsetting certain of the angle of thehead tilt and having the bottom edge of the optical window or opticalcombiner rotated away from the front of the eyewear lens, the line ofsight of the wearer strikes the optical combiner in a mostlyperpendicular manner. (See, e.g., FIG. 55.) In certain cases, this ispreferred and in other cases the bottom edge of the optical combiner isnot rotated away from the eyeglass lens to which it sits in front of.

As shown in FIG. 22, optical window(s) can be rotated counterclockwise2210 and/or clockwise 2220 while supported by the AR Unit. When oneoptical window is used, an optical window can rotate so that the bottomof the optical window located nearest the pupil of the eye is rotatedtemporally. When two optical windows are used (one in front of each eye,for example), each optical window can rotate so that the bottom of theoptical window located nearest the pupil of the eye is rotatedtemporally. Also, when two optical windows are used (one in front ofeach eye, for example), each optical window can rotate so that thebottom of the optical window located nearest the pupil of the eye isrotated nasally. An optical window can be moved horizontally and/orvertically while supported by the AR Unit. The optical window can berotated along the Z axis when not in use such that the bottom of theoptical window is rotated out and up and back.

An optical window(s) can be moved nasally and/or temporally whilesupported by the AR Unit. When the optical window is moved horizontally,it generally is moved to align the wearer's pupillary distance. Thepupillary distance is the distance between the wearer's pupils whenlooking at a particular distance (which is usually far, intermediate andnear) measured under a standard level of illumination. An optical windowcan be moved vertically and/or horizontally when supported by the ARUnit. An optical window can be moved automatically or semi-automaticallyby the AR Unit. An optical window can be moved mechanically or manuallyby the wearer of the AR Unit. The optical window or optical windows canbe moved out of the field of view of the wearer when the AR Unit is notbeing used thus allow for the wearer to have unencumbered vision whenlooking straight ahead or otherwise. In certain embodiments, the opticalwindow can be magnetically detached from the AR Unit and magneticallyreattached to the AR Unit such that the proper optical alignment ismaintained. The mechanism for effecting the movement of the opticalwindow may comprise using a sensor, a controller, and/or a motor. Themotor can be a micro motor. The motor can be mems device.

One, two, or more white LEDs can be utilized within a lightengine.

In certain embodiments, the focal length of a projector or display usedwithin a light engine of the AR Unit can be altered by moving thefocusing lens closer to the projector or further away. The movement canbe by way of MEMs system and/or a micro motor. The movement can beautomatically, semi-automatically, or manually controlled. In certainembodiments, the illumination source illuminates the micro display,light from which is collected, focused and transmitted into a fiberoptic delivery system or a waveguide. The micro-display forms thevirtual image to be projected at a desired distance from the eye of thewearer. The fiber optic, waveguide, or lightguide delivery system cancarry the AR image information to the combiner which is then directed tothe pupil. In certain embodiments, a fiber optic delivery system maycomprise a plurality of optical fibers that end in a second opticalcoupling device which may comprise a prism and/or a combination of, byway of example only, a lens and a prism, or a stack of partiallytransmissive thin layer films. The waveguide or lightguide deliverysystem may end in a second optical coupling device which may comprise aprism and/or a combination of, by way of example only, a lens and aprism, or a stack of partially transmissive thin layer films. Theoptical coupling can include an optical grating. In certain embodiments,a single projector with a beamsplitter can illuminate two opticalwindows.

In certain embodiments, the optical combiner combines light emanatingfrom the projector carrying an AR image information with light comingfrom real objects that the wearer is looking at and thereby enables theAR virtual image to be located at a distance, by way of example only,from 40 centimeters to 6 meters in the real environment. The AR Unit canbe designed to combine and align the wearer's convergence andaccommodation for that of a virtual image seen by the wearer with thatof a real image seen by the wearer.

The AR Unit can support one or multiple cameras. In certain cases, whenmultiple cameras are utilized, they can be spaced to provide for anincreased 3D effect. In other cases, when multiple cameras are utilized,they can be utilized for spatial location. When multiple cameras areused they can be distance separated from one another. When multiplecameras are utilized, one can be located at or near the horizontalcenter of AR Unit's main body and the other attached to a temple of theeyewear or located on or near one of the horizontal ends of the ARUnit's main body. (See, e.g., FIGS. 53-54.) When one camera is utilizedthe camera can be located at approximately the horizontal center of theAR Unit main body. One or more of the cameras can be capable ofcapturing one or both of a still image and video.

By wayof example only, one or more of the waveguide, lightguide, opticalwindow, and/or optical combiner, can be attached to the AR Unit's mainbody located above the eyewear frame, thus providing for a top downoptical combiner or optical window when attached to the AR Unit's mainbody and located in front of the pupil of the wearer when an augmentedreality image is viewed by the wearer. In other embodiments, the opticalcombiner can be attached to the side and come across from a side of theAR Unit's main body.

The image capture system or #8 above can capture photos and HD videos.The image capture system can be a camera. A courtesy light can belocated on the AR Unit to inform an individual whose image is beingcaptured that such an action is occurring. A courtesy light can belocated near or adjacent to the image capture system of the AR Unit.However, it should be noted that a courtesy light can be locatedanywhere on the AR unit such to provide a front facing light. In somecases, a second camera can be attached to the temple and/or to the ARUnit, as shown in, for example, FIGS. 53-54.

In certain embodiments, the optical window(s) can be located in front ofthe lens, further away from the eye (see, e.g., FIGS. 25, 38). In otherembodiments, the optical window(s) can be located behind the spectaclelens closest to the eye (see, e.g., FIG. 24). In still otherembodiments, the lens of the eyewear acts as an optical window andincludes an optical combiner. In this case, the optical combiner can be,by way of example only, a reflector or mirror. Such a reflector ormirror can comprise optical power to reduce aberrations.

When the optical window is located behind the spectacle lens closest tothe eye or incorporated in the spectacle lens, a tunable lens isrequired to properly align the wearer's accommodation and convergencewith that of the virtual and real images. In certain embodiments wherethe spectacle lens is that of a filler lens having no optical power, atunable lens is not required. In certain embodiments this can beaccomplished by mechanically moving a focusing lens closer or furtherfrom the projector or display. When a tunable lens is utilized, suchtunable lenses are known in the art.

In certain embodiments, the spectacle lens of the eyewear acts as theoptical window and/or the optical combiner. In these embodiments, theoptical window/optical combiner is not moveable, and the opticalcombiner must be aligned to the pupil of the wearer. As stated earlier,in certain embodiments, a reflecting material properly aligned acts asan optical combiner. Such a reflective material can be on a surface(inner or outer convex or concave) of the lens or embedded within thelens matrix. When this occurs, the optical combiner can be properlypositioned relative to the pupil of the wearer when the lens is edgedfor the shape of the eyeglass frame and inserted into the eyeglassframe. The optical combiner may be located by way of example only, inthe lens in front of the pupil of the eye of the wearer, in the lensabove the pupil of the eye of the wearer, and/or in the lens above theline of sight of the wearer. Both lenses of the eyewear can eachcomprise one optical combiner. When a lens or two lenses are used as theoptical window/optical combiner, the image being optically communicatedcan be transmitted from the top edge of the lens thru the lens to theoptical combiner which can be incorporated therein or in otherembodiments located on the surface of the lens. The image beingoptically communicated can be projected at the required location on thetop edge of the lens so that it is incident on the optical combinerwithin or on the lens. The top edge of the lens can comprise an opticalcoupler that transmits the optically communicated image. The opticallycommunicated image can be the augmented reality image or the virtualimage that is seen by the wearer of the AR Unit. The upper rim of theeyewear frame front that houses a lens can comprise an aperture to allowthe optically communicated image (e.g., projected image) to betransmitted through the eye frame rim, as shown in FIG. 41. Thisaperture of the eyewear frame can be formed as an oval or rectanglehaving its longest dimension horizontally along a length of the top eyeframe rim of the eyewear frame. This aperture 4100 allows for theoptically communicated image to pass through the frame eye rim and becommunicated to the lens (optical window). In another embodiment, theedge of the lens is formed with a protrusion on the lens itself, near oradjacent to its edge, such that the optically communicated image can becommunicated without the frame eye rim interfering. In aspects, whenboth lenses are used as optical windows comprising optical combiners,the top of each eye frame rim that houses each of the lenses will havean aperture formed therein. In some embodiments, an optical coupler isused to connect the optic transmitting the optically communicated imageto the top edge of the lens. In aspects, the optic transmitting theoptically communicated image is positioned adjacent to, but not bondedto, the top edge of the lens. The top edge of the lens can be shaped tobe flat or of any topography that will best transmit the opticallycommunicated image. In a different embodiment, the edge of the lens isformed with a protrusion of the lens itself such that the opticallycommunicated image can be communicated by the communicating opticwithout the eye frame rim interfering. The communicating optic can becoupled to the protrusion near or adjacent to the edge of the lens. Thecommunicating optic can be bonded to the protrusion near or adjacent tothe edge of the lens. The communicating optic can be placed adjacent tothe protrusion near the edge of the lens. The protrusion near the edgeof the lens can be polished.

In still other embodiments, as shown in for example, FIGS. 50-52, anoptical grating 5010, 5110, 5210 is used to optically communicate theimage from the light engine (e.g., projector or display) to an opticalcombiner via a waveguide 5020, 5120, 5220. In embodiments, the AR Unitmain body includes one waveguide optical combiner of the optical windowfor monocular use or two for binocular use. In FIGS. 38 (front view)-39(top view), a waveguide optical combiner and optical window are depictedas 3850, 3950. The vertical height of the waveguide optical combiner ofthe optical window is adjustable by way of edging the waveguide opticalcombiner of the optical window to the desired vertical height for agiven frame eye size and style relative to the wearer's pupil. Theoptical combiner or optical window can be located with its bottom edgeat or above the top edge of the pupil(s) of the eye(s) of the wearer.The optical combiner or optical window can be located with its bottomedge at or below the lower edge of the pupil(s) of the eye(s) of thewearer. The displayed augmented reality image can be programed to bedisplayed in relation to the usable waveguide optical combiner/opticalwindow dimensions (vertical height and horizontal width). Inembodiments, the bottom edge of the waveguide optical combiner of theoptical window can be set above the top edge of the pupil 5140 as shownin, for example, FIG. 51. At 5140 is where the pupils are located whenthe wearer is looking straight ahead; 5150 is where pupils would be whenthe user tilts the head forward, for example. Alternatively, in FIG. 52,an embodiment is shown wherein the optical combiners make up the fulloptical window(s). In this embodiment, the optical window(s) are of avertical height so that they cover the wearer's pupils even when lookingstraight ahead without the head tilted 5240. The waveguide opticalcombiners/optical windows can be positioned in front of, behind thespectacle lens(es) of the wearer, or embedded within the spectaclelens(es) of the wearer. But in a preferred embodiment, they arepositioned in front of the spectacle lens(es) of the wearer furthestfrom the eyes of the wearer.

Eyewear comes in hundreds, if not thousands, of different styles,shapes, sizes and materials. (See, e.g., FIGS. 5-6.) For the purposes ofminimizing the number or AR Unit main body SKUs (stock keeping units)and to allow the AR Unit's main body to look fashionable when applied tothe eyewear frame, the AR Unit can comprise, by way of example only, oneor more of a compressible and/or formable material. In certainembodiments, the AR Unit's main body will fit on the eyewear framefront. In other embodiments, the compressible material above the eyewearbridge and/or affixed to or embedded in the bottom area of the AR Unit'smain body is preferred or necessary for proper fit. Because of thecurrent invention's ability to fit many types of eyewear frames, one SKU(stock keeping unit) of a design of the AR Unit's main body can beoptimized to fit a plurality of different eyewear shapes and sizes.(See, e.g., FIGS. 7, 45-48.) A separate part can be attached to the oneSKU design to enhance the cosmetic appearance and/or fit of the ARUnit's main body attached to certain eyewear shapes, if necessary. Theseparate part can be a façade that is utilized to cover open spaceformed when the AR Unit's main body is fitted upon the top of theeyewear frame front. In most but not all cases, a façade is utilizedbetween certain locations under the AR Unit's main body and above thetop of the frame front. By way of example only, a façade can be used tofit beneath the bottom of the AR Unit main body and the top of theeyewear frame front superior to the bridge area. In still other cases,multiple facades can be used to cover up multiple openings formed underthe AR Unit's main body and superior to the top of the eyewear framefront. The separate part can be offered as multiple separate parts (orfacades) of different sizes or shapes to the consumer thus allowing forfurther improved fit and/or cosmetic enhancement of the AR Unit's mainbody for even a larger number of different eyewear shapes and sizes. Incertain embodiments a kit of facades are included with the sale of theAR Unit. The separate part can be rigid, compressible, or conformable,depending on the spatial relationship of the bottom of the AR Unit'smain body and the top of the eyewear frame located above the bridge ofthe eyewear front. The invention disclosed herein allows for one ARUnit's main body to fit a plurality of different eyewear styles andsizes, allowing a limited number of different AR Unit main body shapesto fit a majority of eyewear styles and sizes. The invention disclosedherein allows for a limited number of different AR Unit main bodiesutilizing one or more of a compressible material, façade, flexiblestructure of the AR Unit's main body, and/or shapeable portions of theAR Unit's main body such as (by way of example only) the outer AR Unit'smain body covering, to fit the majority of eyewear styles and sizes. Forexample, the invention disclosed herein allows for five or fewerdifferent AR Units utilizing one or more of a compressible material,façade, flexible structure of the AR Unit's main body, and/or shapeableportions of the AR Unit's main body such as (by way of example only) theouter AR Unit's main body covering, to fit the majority of eyewearstyles and sizes. In cases, no compressible material will be needed foradequate attachment to the eyewear frames. (See, e.g., FIG. 12.) Inaspects, a portion of the augmented reality device is flexible, wherebya bendable member is housed within or attached to the flexible portionand whereby the flexible portion of the augmented reality devicesupporting a bendable member rests on top of an eyewear frame front. Itshould be pointed out, that certain embodiments of the AR Unit inventiondisclosed herein can be flexible and others are not flexible but can berigid.

In certain embodiments, the AR Unit has all or part of its memory and/orcomputational requirements off loaded from the AR Unit to that of aremote and/or mobile device. By way of example only, a cell phone orsmart phone case, a smart mobile unit, or a CPU, supports or includesremote memory and a CPU for the AR Unit, whereby the remote memoryand/or CPU communicates with the AR Unit wirelessly or by wire. Inembodiments, the cell phone case or smart mobile unit, or CPU, wouldcomprise the necessary electrical components required to provide suchwireless or wired communication, memory storage and/or retrieval, andremote computation.

As shown in FIGS. 34-37, in certain embodiments, a separate part 3410,3510, 3610 which acts as a facade can be attached to the AR Unit's mainbody as illustrated herein when needed (see also, e.g., FIGS. 10 and45-48). The separate part acts as a façade covering the open space(hole) 3420, 3520, 3620 over the eyewear bridge 3430, 3530, 3630. In oneembodiment of the invention, multiple separate parts would be includedas a kit when the AR Unit is sold (see, e.g., FIG. 37). In certain otherembodiments, one manually adjustable pull-down member found within theAR Unit's main body can be used to cover an open space above the bridgeof the eyewear and beneath the middle of the AR device when theaugmented reality device is positioned on the top of the eyewear front.(See, e.g., FIG. 40.) By incorporating one pull down member within thebottom of the AR Unit's main body, it acts as a façade covering an openspace that will appear when an AR Unit's main body is attached todifferent sizes or different eyewear frame styles. The middle member canbe pulled down further to cover a larger open space or less far to covera smaller open space. When a pull-down member is utilized as a façade,it is integral with that of a portion of the AR Unit's main body. When aseparate part is utilized, it can be part of a kit of separate façadeparts. The separate facade parts can be attached to the AR Unit's mainbody to cover the open space above the bridge of the eyewear frame fromwhich the AR Unit rests upon. The separate façade part can be attachedto the AR Unit's main body by way of example only, a pressureconnection, slide in connection, magnetic connection, mechanical joint,or male-female mechanical connection.

As shown in FIGS. 46-48, in one embodiment, the AR Unit's main body canhave a dividing line 4600, 4700, 4800 that separates the right half fromthe left half. The dividing line allows for the right half to be flexedor rotated from the left half, or vice versa. (See, e.g., FIGS. 46-48;see also FIG. 51.) The degree of rotation or flex can be, in aspects,within the range of 0.5 degrees to 25 degrees. A preferred range isbetween 5 degrees and 15 degrees. In a preferred embodiment, the “total”degree of rotation or flex is 10 degrees relative to one another (eitherhalf). When the AR Unit is flexed in the middle, one or both opticalwindows can be rotated clockwise or counter clockwise, or otherwiseadjusted, to remain properly aligned to receive and display an AR imageto the wearer as described herein. In certain embodiments, the righthalf and the left half remain attached and rotate or flex by way of amechanical member, hinge, formable member, and/or joint. In still otherembodiments, the right half and the left half are totally separated andare two distinct parts.

As shown in FIG. 49, the AR Unit's main body may be raised and loweredabove the eyewear frame front to which it is resting upon. This canoccur, for example, by way of any known mechanical means such as a setscrew(s) 4910. This allows one or more of the wearer, technician,seller, or optician to adjust the AR Unit's main body up and down suchto align the optical window and/or the optical combiner to be positionedas desired in relation to the line of sight of the wearer, or inrelation to a pupil(s) of the wearer. An optical window and/or opticalcombiner can be moved independently of the AR Unit's main body and/orcamera 4930. An optical window and/or optical combiner can be moved asthe AR Unit's main body and/or camera is moved 4920. An optical windowor optical combiner can be moved by way of example only, one or more ofcounterclockwise, clockwise, along the X axis, along the Z axis, and/oralong the Y axis.

In certain embodiments, a tap (or series of taps) of the AR Unit's mainbody, eyeglass frame, or more specifically an eyeglass temple, can turnon and/or off the AR Unit. In certain embodiments, a tap (or series oftaps) of the AR Unit, eyeglass frame, or more specifically an eyeglasstemple, captures an image or video image with a camera or cameras, orimage capture device that is associated with the AR Unit. (In certainembodiments, the camera may be spring-loaded (see, e.g., FIG. 11).) Inother embodiments, the camera is located stationary with the AR Unit'smain body. In aspects, a voice command turns on or off the AR Unit. Inaspects, a voice command triggers a camera or cameras that is associatedwith the AR Unit to capture an image or video. In aspects, a blink of aneye(s) by the wearer turns on or off the AR Unit, or triggers a camerathat is associated with the AR Unit to capture an image or video. Inaspects, a jerk or movement of the head turns on or off the AR Unit. Theelectrical tether or AR Unit's main body may comprise a capacitiveswitch which allows for, by way of example only, a swipe to turn the ARUnit on and, for example, an opposite swipe to turn the AR Unit off. Incertain embodiments, a tilt switch can turn the AR Unit on or off. Whenthe head is looking straight ahead without the wearer's head tilted, thetilt switch can turn the unit off. However, when the wearer's chin istilted down the AR unit can turn itself on. The AR Unit can use AI(artificial intelligence) to learn to differentiate between when thewearer desires to see AR and when the wearer is just looking down bytilting his or her head. Feedback for the wearer on the status of the ARUnit or camera may be provided by a vibrator, buzzer, bell, light,personal assistant, acoustic system, or other ways of communicating withthe wearer.

In certain embodiments, a mostly transparent (or semi-transparent)see-through OLED stack comprises an emissive layer (with four types ofcolored pixels: red, green, blue, and clear), either placed in a singlelayer or three overlapping layers (see, e.g., FIGS. 58 and 59). Themulti-stack emissive layer is capable of improved resolution but lowertransparency. The cathode and the anode may be made of transparent metaloxides, while the hole transport and injection layers may be made oftransparent plastic materials. In embodiments, the transparency of theOLED stack is about 35%, but it may be as high as 50%, or as low as 10%,when, for example, the last layer in the stack shown in FIG. 59 is madepartially reflective.

For the purposes of an embodiment using a see-through OLED opticalcombiner that is useful for the AR Unit disclosed herein, thesee-through OLED transparency should range between 60%-75+%. When thetransparency of the see-through OLED is below 70% the use of the AR Unitis impaired indoors, however the AR Unit can still be used outdoors.When the transparency of the see-through OLED is 70% or above, the ARUnit can be used both indoors and outdoors. In a preferred embodiment,the AR Unit utilizes one or two see-through optical combiners having atransparency of 70% or greater. In another preferred embodiment, the ARUnit utilizes one or two see-through OLEDs having a transparency of 75%or greater. The light transmission of the OLED can be enhanced by theuse of a microlens array.

In certain embodiments, a semi-transparent OLED display supported by anoptical window may be mounted on the inside or the outside surface ofthe optical window (as disclosed herein) and may be used to projectaugmented reality content onto the pupil. In certain embodiments, theOLED display can be the optical window. Such a semi-transparent displaymay be a see-through OLED that comprises a RGB stack and that is drivenby a graphic processing unit. The semi-transparent OLED display compareswith other display technologies in terms of brightness, field of view,and energy consumption (see, e.g., FIG. 60).

The see-through display may be mounted permanently on the AR device, orit may be mounted on an optical window. (See, e.g., FIG. 2.) It may takethe place of the optical window such that it is enabled to be movedupwards or downwards, or it may be attached to an optical window thatenables it to be rotated away when the AR device is not in use. (See,e.g., FIG. 29, 2920.) Accordingly, in aspects, the optical window(s) maybe moved up and out temporally when the AR Unit or system is not beingused. Alternatively, the optical window(s) can be left in a workingposition when the AR Unit or system is not being used and the opticalwindow(s) can be raised vertically when the AR Unit or system is notbeing used. Preferably, the display pivots on its distal end, near theeyeglass frame hinge, and the rotation can take place either in the x,zor x,y planes. (For example, see, e.g., FIG. 22.)

The pixel size of the see-through OLED display may be in the range of1.5-10 microns, preferably 2-3 microns. This display can be 4000×3000pixels. The minimum pixel count is preferred to be 1×106 pixels. Theupper limit of the pixel count is determined by the amount of powerrequired to operate the display. Since OLEDS are current driven (theyoperate mostly between 2-4 volts), the maximum power of the display unit(for each eye) is 750 milliwatts, or about 1.5 watt for both displays,in aspects.

Use of a see-through OLED in the display also may serve to increase thefield of view of the AR image. For example, a field of view of up to 100degrees (e.g., a range of 50-100 degrees) is possible. The binocularfield of view of natural vision is about 110 degrees.

In a certain embodiment, a see-through OLED stack is used, as depositedon a transparent plastic film with barrier properties such as polyimide.The OLED stack is encapsulated in between two layers of flexibletransparent plastic films for durability. The encapsulated stack may befurther mounted on an optical window of the AR Unit's main body astaught herein. This plastic sheet may constitute an additional layer, orit may the same layer as the substrate. (See, e.g., FIG. 4 for apossible layered embodiment.) If one display is utilized, it may bemonocular. If two displays are used, it may be binocular. The opticalwindow(s) may be transparent or partially transparent. It may be coatedwith antireflective coatings. It may be photochromic, electrochromic, orthermochromic. In these embodiments, the optical window(s) can bedarkened in environments with high ambient illumination in order toequalize the relative brightness of the real and the virtual images andlightened in other lighting environments where this is not needed.

When see-through OLED display(s) are utilized as the opticalcombiner(s), the AR Unit's main body can be reduced in size and weight.This is due to the fact that the number of components utilized in thelight engine(s) and optical engine(s) can be reduced. In addition, inmany cases the energy requirements of the AR Unit can also be reduced.(See, e.g., FIG. 3.)

When the optical combiner is a see-through OLED display(s) or the ARUnit utilizes a see-through OLED display(s), the see-through OLEDdisplay is capable of being used for, or as a component for, XR, AR,Virtual Reality, and/or Mixed Reality.

Turning to a few figures, regarding FIG. 58, in a preferred embodiment,the semi-transparent OLED stack is curved in a shape conformal to theeyeglass optics and is equal to or less than the area of the eyeglassoptic and mounted on the eyeglass frame outside the eyeglass optic. Inthis position it forms the virtual image and projects it at infinity andthereby functions as a combiner. In a preferred embodiment, thesemi-transparent OLED or see-through OLED may be shaped to conform withthe outer curve of the lenses providing refractive correction. For thispurpose, the substrate used for the semi-transparent OLED may be a thin,flexible transparent ceramic or glass, or a plastic film. Preferably theglass may be float glass. In one embodiment, the OLED stack may comprisean electrode layer that has been reinforced with a mesh made of a metalnanowire in order to improve transparency of the electrode layer andenhance its flexibility, enabling the semi-transparent OLED to be bentto a shape conformal to the eyeglass optic providing refractivecorrection.

Regarding FIG. 59, MLA is microlens array and Ag mesh is mesh made ofsilver nanowire. (See Shin, S-R, et al., “Improving light extraction offlexible OLEDs using a mechanically robust Ag mesh/ITO compositeelectrode and microlens array.” in J. Mater. Chem., 2018, 6, p. 5444).The enhancement factor caused by the addition of a layer of a microlensarray was reported to be 1.55 in the aforementioned Shin article.

Regarding FIG. 60, this is an example of an electrode layer powering asemi-transparent OLED reinforced with a mesh made of silver nanowires.Light emitted by the OLED stack is nearly Lambertian; in other words, itis emitted equally in all directions. In certain embodiments, thebrightness of the virtual image created by the see-through display asperceived by the retina can be enhanced by providing a layer oftransparent plastic with micro-lenses of the same size as the pixels inthe OLED that collect and collimate the emitted beam. In certainembodiments, a microlens array may be incorporated as an additionallayer in the OLED stack. The microlens array is readily formed bymolding using a soft mold made of PDMS (polydimethyl siloxane), andcombined with a transparent electrode such as an ITO electrode or an ITOelectrode reinforced with a mesh made of silver nanowires. FIG. 60 alsoshows the improvement in mechanical flexibility of the OLED stack causedby introduction of metal nanowire reinforcement.

Regarding FIG. 61, it shows normalized luminance of ITO- and Agmesh/ITO-based OLEDs versus (a) bending radius and (b) bending cycles.

FIG. 62 shows that image intensity and image contrast of the virtualimage may be further enhanced by adding a switchable optical shutterrendering the spaces in which the virtual image is black more perfectlyblack. In a preferred embodiment, a switchable dynamic optical shutteris added as an extra layer in the OLED stack, facing outwards. Theshutter is pixilated and each pixel in the shutter can be addressedindividually. The shutter is activated to cut off ambient illuminationfrom being incident on the OLED only in the dark areas of the virtualimage. A liquid crystal based dynamic switchable optical shutter, inembodiments, may improve image contrast of the virtual image.
